The bulk update request #10578 has been rejected.
create implication phorusrhacos (3) -> terror_bird (107)
create alias terrobird (0) -> terror_bird (107)
Reason: Phorusracos is the very genus of terror birds the family is named after, and there are 3 posts on the site tagged as it. The tag, however, implicates nothing.
As for the alias, both seem to currently be in use but there seems to be very high overlap and I don't see any difference between these two spellings.
EDIT: The bulk update request #10578 (forum #441347) has been rejected by @Bugabond.
